Corneal ultra-high relocation OCT

Optical coherence tomography (OCT) has revolutionized ophthalmology. Since its introduction more than 20 years ago there was an enormous improvement in resolution, speed and sensitivity. We present a method for imaging the human cornea with a resolution of approximately 1.3 micrometers. This allows for the visualization of corneal tissues with unprecedented precision enabling visualization of structures that could not be seen before. Most importantly the pre-corneal tear film can be visualized and quantified. Data in patients with dry eye syndrome are presented as well as data on the effect of lubricants on tear film thickness. Furthermore the present talk will focus on the imaging of corneal pathologies using this novel device.
